Asking again if you have knowledge of installing ZHP gs20 software into 325 gs20? Or atleast pointer in right direction so I can determine plausibility if this install.

Hi, i did not try it, but in E46 sp-daten is ZUSB 7557994 for FA 767 Performance Package or 330I Sport version. I think this is ZHP software for gs20. You can try to flash it with Winkfp, but its for 330i and i read that ZHP had a shorter differential also. There are also ZUSB for 325i with FA 204 Shorter final drive ratio.

I suppose I would have to try and add fa 767 to my vo and see if it takes the flash. Greatly appreciate the info. I hadn’t seen that befor in the 1000’s of pages read. Also does the same ZUSB cover the FA 204?
Have to hanger at that one to see. May just change pressures, to trick the tranny into shifting faster and firmer. I’ll give it a go tomorrow and let you know how it goes. Delete current tranny vo’s and add FA 767 so maybe they do not try to override or interfere with one another .

Thanks Raw!
